The Mountain Rose crags are home to 11 sport climbs ranging in difficulty from 5.8 to 5.12b and 6 trad lines from 5.5 to 5.10. The crags sit across the river and uphill of Castle Rock to the south along the aqueduct path. These two side by side crags face Northwest and get afternoon sun. They are a great place to find shade on a Summer morning. These crags do not have the striking crack lines, smooth granite, and long routes of Castle Rock. Much of Mountain Rose Crags was dynamited to build the aqueduct, & this blasted rock varies in quality from solid to very decomposed. 8 sport routes & 2 trad routes ascend the quarried rock.

The East (left) crag is the larger with routes varying in length from 50 to 80 feet. Most of the routes are on this crag including the routes that ascend natural rock (that wasn't dynamited). The two classic sport climbs on natural rock are "Ancient Of Days" (5.9-) & "Sick Puppy" (5.12b) a desperate slab.

The West (right) crag is smaller with only 4 routes varying in length from 30 to 60 feet. This crag has the easiest sport route "Around The Corner" (5.8).

These crags are an excellent warm-up before heading to the 5.13 routes on the Frisky Cliff. They sit in a beautiful spot, high above the canyon floor with a great view of Castle Rock's south face. Enjoy the flowers & clean mountain air.

The first routes were established around 1990. They were minimally bolted without top anchors. Starting in 2005, numerous sport routes have been established & several older routes have been retrobolted. This a now a fun area with safe routes.

Getting There

From the right side of Castle Rock, cross the bridge & walk right along the base of Broken Rock. The first section is just above the stream. At High water flows it requires a short scramble on a slab to gain a path through the boulders. Follow the base of Broken Rock to its upper right side & the bouldering on the far right of The Overlook. Walk right (south) around a fallen tree & then back left uphill. Walk uphill for a few hundred feet to the flat path along the aqueduct. You will see several manhole covers & hear flowing water. Walk right (southwest) on this wide roadbed path for 400 feet to the left side of the East Mountain Rose Crag. Continue right to your chosen route.


This crag lies close to the Barker to Kossler Reservoirs pipeline route that was constructed in 1909.

Thanks, Tony. I am not sure how to turn a page over to someone else. If you know how, that would be great. Much appreciated. Apr 15, 2015

Agreed. I'd think it most appropriate to edit this page without completely changing the expressed opinions. I think appropriate amendment is in order though. The Admins are welcome to referee that. I'm not terribly invested in it one way or the other, other that to insure that a reader is informed that there are still some older, particularly loose/dangerous/low quality climbs up there and not to get onto any given climb expecting that they are all good.
